To all whom it may concern:

Be it known that ll, Henman ERICKSON, a citizen of the United States,residing at Donnybrook, in the county of Ward, State of North Dakota,have invented certain new and useful improvements in Pliers; and li dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

rllhis invention relates to new and useful improvements in pliers or thelike, and is particularly directed. to the provision of such a devicewherein a relatively great leverage is obtained.

The object of the present invention resides in the provision of a pairof pliers or the like having its parts so arranged that a relativelygreat amount of leverage is obtained without materially complicating thestructure thereof or causing it to lose any of the advantages normallypossessed by such a device.

lt is also the object to provide such a device wherein the shearingstrain normally imposed on the pivot of the jaws is distributed in suchmanner as to substantially `strengthen the structure of the device.

With the above and other objects and advantages in view, the inventionresides more particularly in the novel combination, and formation andarrangement of parts hereinafter described and specifically pointed outin the appended claims.

Reference is had to the accompanying drawing wherein similar charactersof reference designate corresponding parts throughont the several views,and in which:

Figure 1 is a side elevation of a pair of pliers constructed inaccordance with the present invention. Fig. 2 is a detail sectional viewon the line 2-2 of Fig. 1.

Referring now more particularly to the accompanying drawings, theimproved pliers are shown as comprising a shank portion 5 having one endbent laterally as at 6 to form the fixed jaw of the tool, this xed jawbeing preferably 'concaved and provided with teeth 7 adjacent its innerend so that it may I ,more readily grip a section of pipe or the like.The shank is slotted at 8 for the major portion of its length. Pivotedat 9 in this slot is the movable jaw l0, which is provided inwardly witha concave toothed portion ll coacting with the portion 7 of the fixedjaw. The other end of the shank is offset toward the jaws and extendedto provide a handle 12. For operating the movable jaw, a second handle13 is provided which has one end laterally bent at 14 and which has itsangle portion pivoted at l5 in the slot of the shank 5 with its lateralextension 14 disposed parallel to the movable jaw. A air of links 16pivotally connect the end o this extension and the intermediate portionof the movable jaw.

From the foregoing it is seen that a simple tool has been provided whichis' durable in use and which possesses a relatively great leverage.

Although the jaws have been shown as a specific form of pliers, it isseen that any type of jaws may be used without departing from the spiritof the invention. For instance the jaws may have their ends bent to formpincers.

at is claimed is:

l. A tool of the class described comprising' a shank member having oneend extended to form a handle, a fixed jaw on said shank; a movable jawpivoted to said shank, a second handle member pivoted to the shank, anda link pivotally connecting said second handle member and the movablejaw.

2. A tool of the class described comprising a shank member, one end ofsaid shank being odset and extended to form a handle, a fixed jawon saidshank, a movable jaw pivoted to said shank, a second handle memberpivoted to the shank adjacent said odset,

and laterally directedadj acent4 thereto and a link pivotally connectingsaid lateral portion and the movable jaw. lin testimony whereof, liaiiix my signa'- ture, in the presence of two witnesses.
